Organophosphorus pesticides (OPs) are widely used in agricultural production, posing a great threat to human health and the environment. Given that different OPs present different toxicology and toxicities, identifying individual pesticide residues becomes important for assessing food safety and environmental implications. In this work, a kinetics difference-driven analyte hydrolysis strategy is proposed for the first time and validated to identify p-nitrophenyl pesticides by developing an organophosphorus hydrolase-like nanozyme-coded sensor array. Ultrasmall bare CeO(2) nanoparticles were sy...
